    Present-day evolution in communication and information technology dispenses straightforward and effortless access to data, but the most noteworthy condition is the formation of secure communication. Numerous approaches were designed for safety communication. One of the crucial approaches is image steganography. Moreover, provisioning of information security services is arrived at via cryptosystems where cryptosystems make certain the secure messages transmission between the users in an untrustworthy circumstance.  The conventional method of providing encryption and signature is said to be first signing and then encryption, but both the computation and communication costs are found to be high. A certificateless signcryption mechanism is designed to transfer the medical data or images securely. This mechanism will minimize the storage and verification costs of public key certificates. The author of this article proposes a method named Lagrangian recurrent Steganalysis and Hyper Elliptic Certificateless Signcryption for transferring the medical data or images securely. In two sections the LRS-HECS method is split. They are medical image steganalysis and certificateless signcryption. First with the Chest X-Ray images obtained as input, a Codeword Correlated Lagrangian Recurrent Neural Network-based image steganography model is applied to generate steg images. Second, to transfer the medical images securely the steg images provided as input is designed a model named a Hyper Elliptic Curve-based Certificateless Signcryption. The issue of providing the integrity and validity of the transmitted medical images and receiver anonymity is addressed by the application of Hyper Elliptic Curve. Chest X-Ray pictures were used in experimental simulations, and the findings showed that the LRS-HECS approach had more advantages over existing state-of-the-art methods in terms of higher peak signal to noise ratio with data integrity and with reduced encryption time and transmission cost

    Background. Hypertension is extremely prevalent in patients with diabetes. Limited data exist on utilizationpatterns of antihypertensive in this population are consistent with evidence-based practice guidelines.Objective. To evaluate utilization patterns of antihypertensive agents among diabetic patients with hypertension.Design. Retrospective descriptive cross sectional.Patients / Participants. 149 patients with diabetes and hypertension from outpatient department at FamilyMedicine Hospital, Ahaderfieda. Khamis Mushait, K.S.A.Results. Over 43% of patients were receiving calcium channel blockers (CCB), 36.2 % of received angiotensinconverting enzyme inhibitors (ACEI), followed by angiotensin receptor blockers (ARBs) (34.9%),diuretics (34.2%) and β -blockers (16.2%). Patients on monotherapy were mostly receiving CCB (34.3%)and ACEI (29.9%). The majority (55.03%) of treated patients were on multidrug regimens. In patientswith coronary artery disease (CAD), a diuretic with ACEI (25%) and calcium channel blocker with angiotensinreceptor blocker (25%) was most commonly prescribed.Conclusions. Patterns of antihypertensive therapy were generally consistent with international guidelines.Areas of improvement include increasing ACEI/ARB and diuretic use, decreasing the number ofuntreated patients, and increasing the proportion of patients with controlled BP in this population.Antecedentes.

    In solid organ transplant patients, non-melanoma skin cancer remains a leading cause of mortality. The most common skin malignancies in solid organ transplant patients are squamous cell carcinoma (SCC) and basal cell carcinoma (BCC). In organ transplant patients, SCC is 100 times more prevalent, and BCC is 10 times more prevalent than in the general population. Many risk factors for developing such malignancies are equivalent to those in the general population. However, in the transplant population, such cancers occur at an earlier age, act more aggressively, and often appear at multiple locations. Thus, assiduousness on the patient\u27s part and healthcare providers is the highest priority. The concurrence of SCC and BCC together is rarely encountered in a post-transplant individual. We report a rare case of coexistence of SCC and BCC in the same patient. A 63-year-old man had been diagnosed with SCC and BCC simultaneously by a punch biopsy performed at two different scalp lesions of different diameters. This review describes an unusual occurrence of both skin cancers concurrently in a kidney transplant recipien

    Air Conditioning Using Radiant Cooling System

    A Radiant cooling system alludes to a temperature-controlled surface that cools indoor temperatures by evacuating sensible heat and where the greater part of heat exchange happens through thermal radiation. Heat will spill out of objects, occupants, equipment and lights in a space to a cooled surface the length of their temperatures are hotter than that of the cooled surface and they are inside the observable pathway of the cooled surface. The procedure of radiant exchange negligibly effects on air temperature, yet through the procedure of convection, the air temperature will be brought down when air interacts with the cooled surface. Radiant cooling system utilizes the inverse impact of Radiant cooling system, which depends on the procedure of heat spill out of a warmed surface to items and inhabitants

    Background: This study was done to know whether patients with hip injury have pre-existing osteoporosis due to which, the patient sustained the fracture, subsequent fracture of the contralateral hip, any osteoarthritic changes of the contralateral hip at the time of index fracture, and ten-year probability of a major osteoporotic fracture by calculating fracture risk assessment percentage (FRAX%).   Methods: 34 patients were evaluated for age, gender, body mass index (BMI), fracture type, Singh index, bone mineral density (BMD), T-scores using dual-energy X-ray absorptiometry (DEXA) scan, and ten-year probability of fracture using FRAX%.   Results: Average age of the patients with hip fractures was 72.1 years. About 85% of patients were women. 67.6% of the patients were with BMI of 18.5-25 kg/m2. The Singh index for osteoporosis fell in grades 2 and 3 in most patients. The mean interval between index fracture and contralateral hip injury was 4.25 years. Osteoarthritis of the contralateral hip was seen in 9%. The probability in ten years of hip fracture in 30 indexed patients using the FRAX% tool was 15%, and for 4 patients who were having bilateral hip fractures was 22.75%. There was a significant relationship between FRAX% with the Singh index and osteoarthritis of the contralateral hip. FRAX% was high in female patients.   Conclusion: Contralateral hip fracture in patients with osteoporosis was high in women and patients with low and high BMI. Fractures were also high in patients with low Singh index and T-scores. FRAX% increased with an increase in age and increased with a decrease in T-score.

    We investigated what proportion of the population acquired severe acute respiratory syndrome coronavirus 2 (SARSCoV- 2) infection and whether the herd immunity threshold has been reached in 10 communities in Qatar. The study included 4,970 participants during June 21-September 9, 2020. Antibodies against SARS-CoV-2 were detected by using an electrochemiluminescence immunoassay. Seropositivity ranged from 54.9% (95% CI 50.2%-59.4%) to 83.8% (95% CI 79.1%-87.7%) across communities and showed a pooled mean of 66.1% (95% CI 61.5%-70.6%). A range of other epidemiologic measures indicated that active infection is rare, with limited if any sustainable infection transmission for clusters to occur. Only 5 infections were ever severe and 1 was critical in these young communities; infection severity rate of 0.2% (95% CI 0.1%-0.4%). Specifi c communities in Qatar have or nearly reached herd immunity for SARS-CoV-2 infection: 65%-70% of the population has been infected.This study was supported by the Hamad Medical Corporation, Ministry of Public Health, and the Biomedical Research Program and the Biostatistics, Epidemiology, and Biomathematics Research Core, both atScopu

    BACKGROUND: Qatar experienced a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) epidemic that disproportionately affected the craft and manual worker (CMW) population, who comprise 60% of the total population. This study aimed to assess ever and/or current infection prevalence in this population. METHODS: A cross-sectional population-based survey was conducted during July 26 to September 09, 2020, to assess both anti-SARS-CoV-2 positivity through serological testing and current infection positivity through polymerase chain reaction (PCR) testing. Associations with antibody and PCR positivity were identified through regression analyses. RESULTS: The study included 2641 participants, 69.3% of whom were <40 years of age. Anti-SARS-CoV-2 positivity was 55.3% (95% CI, 53.3%-57.3%) and was significantly associated with nationality, geographic location, educational attainment, occupation, and previous infection diagnosis. PCR positivity was 11.3% (95% CI, 9.9%-12.8%) and was significantly associated with nationality, geographic location, occupation, contact with an infected person, and reporting 2 or more symptoms. Infection positivity (antibody and/or PCR positive) was 60.6% (95% CI, 58.6%-62.5%). The proportion of antibody-positive CMWs who had a prior SARS-CoV-2 diagnosis was 9.3% (95% CI, 7.9%-11.0%). Only seven infections were ever severe, and only 1 was ever critical-an infection severity rate of 0.5% (95% CI, 0.2%-1.0%). CONCLUSIONS: Six in every 10 CMWs in Qatar have been infected, suggestive of reaching the herd immunity threshold. Infection severity was low, with only 1 in every 200 infections progressing to be severe or critical. Only 1 in every 10 infections had been previously diagnosed, which is suggestive of mostly asymptomatic or mild infections
